381957 - When iframes are displayed, a large black border appears in the top and left sides of the frame.

Status: RESOLVED DUPLICATE of bug 381746

(Core :: Layout, defect)

Description

[David Turner]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a5pre) Gecko/20070524 Minefield/3.0a5pre
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a5pre) Gecko/20070524 Minefield/3.0a5pre

As far as I can tell, in most cases the iframe(for the chatbox) has the black border everytime.  It only recently started doing this since I upgraded from a previous minefield a few days ago.  Changing the text size fixes it for some reason though.

This occurs on the adsense website aswell(as you are logging in)

Reproducible: Always

Steps to Reproduce:
1.Refresh
Actual Results:  
A black border appears in the top and left sides of the iframe at the bottom of the page.

Expected Results:  
Proper background for the iframe should be displayed instead of the black border.

I was using the default theme at the time, and the only active extension is adblock plus.

I am seeing the same thing with regular frames.  I have an html page that loads 4 tinderbox panels in frames that I sometimes load into my sidebar.  This is now sometimes showing 3/16" black stripes between the frames.  I am sure this belongs in core somewhere probably either layout or gfx.  I will see if I can narrow down a regression range if I can come up with a test procedure that reliably reproduces the issue.

This is a regression caused by the checkin for bug 380438.  Verified by backout.

Well, if I had been paying more attention I could have saved time as someone had already marked this bug dependent on bug 381746.

In any event, I have verified that the patch attached to bug 381746 fixes both the URL mentioned in this bug and the issue with my sidebar page that uses a frameset.
